MRO has shifted from the cruise phase to Approach phase. Apparently, the trajectory is so good that TCM-3 was cancelled. This is good news for the prospects for a long life for MRO supporting future missions. TCM-4 is on Feb 28, and MOI on March 10. Only 5 weeks away!

I thought only the second "Documentation" link was reserved for team access (i.e., requires a userid and password). It looks as if the first tree is as well. |

I generated a view of Earth as MRO comes out of occultation on March 10th, based on the "ideal" NAIF kernel:
 The above is in spacecraft time not accounting for speed of light. The signal would get to Earth 11 minutes, 58 seconds later, at 22:16:00 UTC (5:16pm EST) . -------------------- |

QUOTE (djellison @ Mar 1 2006, 09:28 AM) 1.14 degrees for HiRISE - which is just a tiny bit more than this much Even so, at HiRISE resolution of 1 urad/pixel, Earth being 59 urad (0.0033 deg) across would be ~59 pixels. Approximately this resolution (blown up to 512 pixels across):  On the Earthrise time for the HGA, I don't suppose that the Mars atmosphere affects the X-band very much? -------------------- |
